ROOFING.

SPECIFICATION forming part of Letters Patent No. 359,925, dated March 2.2, 1887.

Serial No. 153,473. [No model.)

To @ZK zzz/0121, it may concern,.-

Be it known that I, CLINTON FRENCH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Roofing; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in roofing in which the roof-boards are covered with ordinary rooting-paper or so-called roofing-felt,7 the sheets thereof preferably running crosswise of the root and overlapping, lik e shingles. This foundation is covered with coaltar or other suitable binder, into which, in the liquid condition, the binder is applied to the roof. toofing-slates are embedded so as to cover the rool'without the slates overlapping each other. The joints between the slates are iilled with coaltar, or whatever is used for a binder, which completes the roof, the object being to provide a cheap waterproof slate roof adapted to a slight grade or pitch, and that may be walked upon without danger of breaking the slates.

In the accompanying drawings, Figure l is a View in perspective showing the const-ruction of inyimproved roof. Fig. 2 isa vertical section ol" the same.

A represents the roof-boards, and B the sheets of rooting-paper, or so-called rootingfelt. These sheets entend preferably cross wise of the roof and overlap each other, like shingles, so that the paper is preferably about four thicknesses, (more or less.) Next, t-he root' is coated with coal-tar or other suitable waterproof binder, the same being heated to reduce it to a liquid condition. Into the binder, while the latter is in a plastic condition, rooing-slates C are embedded. The slates are arranged side by side, but do not overlap. The joints between the slates are lled with coal-tar, or whatever is used for a binder, and this latter opera-tion completes the roof. Such roofs are practicable with as little grade as a tin roof, und are as effectually tire and water proof as the best metal roofs, and are much less expensive. As theslates do not overlap, a comparatively small number of slates cover the roof, and these being firmly embedded in the coaltar or other binder may be walked upon at pleasure without any dan ger of breaking the slates.

My improved roof does not readily transmit heat, and therefore tends to render the house cool in summer and warm in winter.

Owing to the durability of the materials used, the roof is likely to last as long as the roof-boards, and these latter, being protected against moisture from without and having no tendency to condense nioistu re on the inside, will last, ifof good quality, for generations.

Asphaltum in various conditions may be used for a binder; but I prefer the coaltar on account of its cheapness.

I am aware that a roof consisting of roof boards covered with sheets of felt laid side by side, the top layer of the latter being coated with a plastic composition, and slabs or slate laid on said composition` is not new, and hence I make no claim, broadly, to such construe tion.

1What I claim is- A roof consisting, essentially, of roof-boards covered with roong-paper,or so-called roofing-felt,77 the sheets thereof overlapping, so as to form several thicknesses, a coating ol' coal tar or other suitable water-proof binder ap plied in a liquid condition to the rooting paper, and rooting-tiles arranged side by side without overlapping, and embedded in such binder while the latter is in a plastic condi tion, the joints between the tiles being filled with such binding material, substantially' as set forth.

In testimony whereof I sign this specifica tion,in the presence of two witnesses, this 18th day of N ovember, 1885.

CLINTON FRENCH.
